The free energy for ATP hydrolysis in vivo is greater than the standard free energy change of -30 kJ mol-1 because additional energy sources provided by the cell.

These sources include the proton motive force, the binding energy of ADP from the cytoplasm, and the ATP concentration gradient. The proton motive force is generated by the movement of protons across the membrane, driven by the difference in the proton concentrations on either side of the membrane.

The binding energy of ADP from the cytoplasm is a consequence of the ionic interactions between the ADP molecule and the negatively charged cytoplasmic side of the membrane. Finally, the ATP concentration gradient is created by the action of the ATPase enzyme, which actively transports ATP from the cytoplasm to the extracellular side of the membrane.

Explanation:

Theories have to be proven, whilst hypotheses is an experiment that is carried out without yet knowing the outcome.

Since 3% of the original radioactive carbon-14 is still radioactive, the carbon-14 radioisotope has undergone five half-lives.

Half-life of a substance is the time it takes for half the original amount of the substance to decay.

Radioactive elements decay spontaneously according to their half-lives.

Since 3% of the original radioactive carbon-14 is still radioactive, the number of half-lives undergone is determined as follows:

After one Half-Life, 50% remains

After two half-lives, 25% remains

After three half-lives, 12.5% remains

After four half-lives, 6. 25% remains

After five half-lives, 3.125 % remains.

The equation \(M^(^1^) = TB\) represents a mathematical relationship between the variables M and T, where M is raised to the power of 1 (\(M^(^1^)\)) and is equal to TB. The perimeter of the equation \(M^(^1^) = TB\) is given.

In mathematics, the term "perimeter" usually refers to the total length of the boundaries or the outer edges of a shape. However, in this context, it seems that the term "perimeter" is being used metaphorically to represent the overall significance or scope of the equation \(M^(^1^) = TB\).

This equation may be interpreted as a simple linear relationship between M and T, where M is equal to T multiplied by B. The exponent of 1 in M indicates that it is not being raised to any power, so it essentially represents M itself. Therefore, the equation simplifies to M = TB.

By examining the equation M = TB, we can infer that the significance or "perimeter" of this equation lies in the relationship between M, T, and B. The equation suggests that the value of M depends on the product of T and B. In other words, M is directly proportional to the multiplication of T and B.

The ganglia located lateral to the vertebral column are part of the sympathetic nervous system.

The sympathetic nervous system is a division of the autonomic nervous system that is responsible for the body's response to stress, emergencies, and physical activity. It works in opposition to the parasympathetic nervous system to maintain homeostasis and regulate various physiological functions. The sympathetic ganglia are clusters of nerve cell bodies located outside the central nervous system and are involved in the transmission of signals within the sympathetic division.

The ganglia located lateral to the vertebral column, known as the sympathetic chain ganglia or paravertebral ganglia, are a series of interconnected ganglia that run parallel to the spinal cord on both sides. These ganglia receive preganglionic fibers from the spinal cord and relay the signals to postganglionic fibers, which innervate various target organs and tissues. The sympathetic chain ganglia play a crucial role in coordinating the sympathetic response by transmitting impulses and facilitating the activation of various physiological responses such as increased heart rate, dilation of blood vessels, and release of stress hormones.

Therefore, the effective spring constant of the DNA molecule is

\(1.98 x 10^-10 N/m.\)

A molecule of DNA (deoxyribonucleic acid) is a long, double-stranded helical structure that encodes genetic information.

It is made up of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base. DNA is responsible for the genetic makeup of living organisms and is essential for the inheritance of traits from parents to offspring. Now, let us calculate the effective spring constant of the DNA molecule.

The length of the molecule of DNA = L = 2.34 m

Compression = 1.35 %

= 0.0135

Length after compression = L'

= L - ΔLΔ

L = 0.0135 x 2.34

= 0.03159 m

Charge on each end = q

= 1.6 x 10^-19 Coulomb

The Coulomb constant = k

= 9 x 10^9 Nm^2/C^2

The effective spring constant = k'

Using Coulomb's law, we can determine the force of repulsion between the two charges:

F = kq^2/L'^2

Since the helical molecule acts like a spring, it will exert a force opposite to the repulsive force. The effective spring constant, k', can be determined using the following formula:

F = k'xΔL

Therefore,k' = F/ΔL

Substituting the given values into these formulas:

\(F = 9 x 10^9 x (1.6 x 10^-19)^2/(0.03159)^2\)

= 6.27 x 10^-12 NK

= F/ΔL

\(= 6.27 x 10^-12/0.03159\)

= 1.98 x 10^-10 N/m

Therefore, the effective spring constant of the DNA molecule is 1.98 x 10^-10 N/m.

An increase in the price of wheat would lead to a decrease in the supply of straw. This is because farmers would allocate fewer resources to the cultivation of other cereal crops, reducing the production of straw as a byproduct. Therefore, the correct answer is D) Supply decreases.

An increase in the price of wheat would affect the supply of straw by decreasing it. When the price of wheat rises, farmers have a greater incentive to allocate more resources towards growing wheat rather than other crops. Since straw is a byproduct of cereal crops like barley, oats, rice, rye, and wheat, an increase in the price of wheat would lead farmers to focus more on producing wheat, reducing the production of other cereal crops.

As a result, the supply of straw would decrease because farmers are allocating fewer resources to the cultivation of crops that generate straw as a byproduct. This decrease in supply would be represented by a movement down and to the left on the supply curve, as less straw would be available at each price level.

To illustrate this, consider a hypothetical scenario where the price of wheat increases. Farmers, motivated by higher profits, would shift their production towards growing more wheat. This would result in less land, labor, and resources being allocated to other cereal crops, ultimately reducing the overall production of straw. Consequently, the supply curve for straw would shift to the left, indicating a decrease in the quantity of straw supplied at each price level.
